Abstract

The competence of mathematical communication skill is one of the main factors in learning Mathematics; however,

the reality in learning mathematics shows that the students’ ability of mathematical communication is still low. The

main issues of this study is to analyse the students 'mathematical communication skills using The Learning Cell

model and expository learning and to analyze the effect of the application of The Learning Cell model on students'

mathematical communication skills. The research method used was a quasi-experimental method with research

design of Two Group Randomized Subject Post-Test Only. To know the effect of The Learning Cell model's

treatment of mathematical communication skills used Effect Size formula. The total sample was 87 students

consisted of 44 students of experimental group and 43 students of control group. The technique of data collection

for students' mathematical communication skills used the test instrument on the sub-subject of building a flat side

space. The results show that the students’ mathematical communication skills are taught with The Learning Cell

model is higher than the students' mathematical communication skills with those who taught with expository

learning and the Effect Size is in the medium category. The indicators of mathematical communication skills in this

research are: (1) representing real objects, drawing diagrams or tables in the form of ideas and mathematical

symbols, (2) explaining ideas, situations and mathematical relations in writing using real objects, images, and

algebraic expressions, (3) declare everyday events in language or mathematical symbols or arrange mathematical

models of events. So, The Learning Cell model is one of mathematics learning that can be used to improve the

students' mathematical communication skills.

1 INTRODUCTION

Communication skill is one of the aims of

mathematics learning, so needed a good ability to

communicate for achieving the purpose of

mathematics learning. The importance to have the

communication skills, especially in Math lessons

which are reinforced by the experts’ opinion. Prayitno

(2013: 566) states that mathematical communication

is needed by the people to communicate ideas or to

solve mathematical problems, either in spoken,

written, or in visual, such as in mathematical learning

or outside of it. According to Polla (Isrok'atun, 2009:

8) mathematical communication is one of the

important factors in the learning process of

mathematics both inside and outside the classroom.

Communication handles an important action in

mathematics. Anyone who has a special interest in

mathematics will need communication should always

add his/her information as much as possible.

However, the reality in learning mathematics,

the students’ communication skills are still in low

level. Based on the interview results with Math

teachers at SMPN 3 Tangerang Selatan, students are

rarely use mathematical communication skills, so

they are difficult to communicate in mathematics,

using symbols and translating and developing them in

ordinary language or others. This case as result of the

teaching applied in the school is the expository or

teacher centered learning, where the teacher is still

dominant in explaining the subject matter in the class

and the students get less opportunity to explore their

skills to communicate their ideas in mathematic.

Awa's research result (2013) suggests that the highest

indicators of students’ mathematical communication

skills are the abilities to declare or illustrate

mathematical models into the form of mathematical

ideas. According to LACOE, the appropriate way to

develop students' mathematical communication skills

is in group discussion. In the process of discussion

will exchange of ideas and opinion between students.

This will provide an opportunity for students to build

up their understanding and communication skills of

mathematic.

Indicators of mathematical communication

skills used in this research are:

1) Represents real objects, images, diagrams or

tables in the form of ideas and mathematical

symbols

2) Describe ideas, situations and mathematical

relationships in writing using real objects, images,

and algebraic expressions

3) Stating daily occurrence in a language or

mathematical symbol or composing mathematical

model of an occurrence

An alternative model of learning that can

improve students' communication skills is The

Learning Cell model created by Goldschmid in 1976

from Switzerland and then developed again in China

by Yu, Yang, and Cheng in 2015. The Learning Cell

model is a series of learning activities where at each

stage of learning requires students communicate their

own ideas and opinions to other students actively

(Goldschmid, 1976: 20).

The Steps of The Learning Cell in this study are

as follows:

1) Openness

Teachers provide problems those produce variety

responses from students about the issues or topics

given at the beginning of the lesson. From their

answers, then the teachers give tentative or

temporary conclusion. Students list the questions

after looking at the problems which the teachers

revealed, and the question can be asked to other

groups to get the answers.

Figure 1. The Openness of the Learning Cell Principles

The open source of learning according to the

picture above comes from generative information,

learning tools that can openly access learning

content, an ontology environment and classroom

learning activities. Educators present an open

source of learning so that it can trigger various

responses from learners who can develop an

existing learning resource.

2) Social

Then the teacher divides some groups are even

numbered and odd group. The odd group discuss

about the content of lesson A, while the even

group learn lesson content B. Then each student

in the group exchanges information about the

content of the lesson discussed. In other hands,

each group has to make 2 questions; the odd group

makes the question for material B which the even

group discussed, and also even group ask for the

odd group material.

3) Evolvable & Context-Aware

After learning the lesson content and preparing 2

questions, every student in group pairs to the other

group. One of odd group paired with who in even

group (small groups). Activities include asking

and answering questions those prepared each

other between the groups based on their own topic

or material. During this process, the teacher

supervises from one couple to another; provides

confirmation or feedbacks to the students.

Context-Aware is a contextual awareness when

students realize what learning or learned at the

meeting. Contextual awareness showed from the

student's question whether they really investigate

for the material discussed or from their reply.

4) Cohesive

All students summarize the materials in

accordance with the results of questions and

answers with friends. The results of these

conclusions are summarized, which is used as the

learning resources expand in accordance with the

learners’ understanding. The conclusions are

presented by one member of the group in front of

the class.

The application of The Learning Cell model is

expected to get the widest opportunity for students to

express their mathematical ideas, expresses or clarify

their ideas both orally and in written one. Marta

Cahyaningrum, et al. (2012) in her research explained

that the average learning outcomes of students whose

learning using The Learning Cell learning is higher

than the average of student learning outcomes that get

conventional learning. Rita Khotimah & Mukhafifah

(2011) in their research reveal that there is the effect

of student learning activity on student's mathematics

learning achievement.

Based on the above description, the researcher

feels the need to do research with the title “The Effect

of The Learning Cell Model to Students’

Mathematical Communication Skills”.

The problems that will be discussed in this

research are (1) how is the students’ mathematical

communication skill those using The Learning Cell as

learning model and those using conventional

learning? (2) Are the students’ mathematical

communication skills those use The Learning Cell as

learning model higher than those use conventional

learning model?

The purposes of this research are: (1) to analyze

the students’ mathematical communication skills of

the students whose use The Learning Cell and

conventional learning model, (2) to analyze the effect

of the Learning Cell Model for students'

mathematical communication skills.

While the hypothesis in this study, namely "The

students' mathematical communication skills those

using The Learning Cell are higher than those using

conventional learning model".

2 METHODS

The method used in this study is the quasi-

experimental method, which the researchers

unavailable to fully control to the other factors that

influence the variables and experimental conditions.

Selection method based on considering the research

characteristic which intended to analyze the effect of

application of The Learning Cell to students'

mathematical communication skills. The research

design used was posttest-only control group design by

taking two randomly selected classes/groups to be

used as control group and experimental group. In the

experimental group was given special treatment in the

form of learning by using The Learning Cell.

Meanwhile in the control group, researchers

conducted a learning process used expository

strategy. Then, both groups were given a post-test to

obtain the empirical evidence as seen in the final

result, to know whether there is a difference between

the experimental group and the control group.

The affordable population in this study were all

students in SMP Negeri 3 Tangerang Selatan class

VIII registered in the even semester of academic year

2016/2017 consisting of 9 classes. The sample of this

study was chosen by using simple random sampling

technique from an affordable population.

The instrument used in this study is a test

instrument in the form of an essay test to measure the

mathematical communication skills of junior high

school students. The instrument consisted of 6 point-

shaped questions to be given to the experimental

group and the control group after both of them had

completed the overall learning with the subject of

building a flat side room. Instruments tested to both

groups have previously been designed by the

researcher by making a grid on the subject of building

a flat side room adapted to the indicator of the

mathematical communication ability to be measured.

After that, the researchers made scoring guidelines

for assessing student answers. Scoring guidelines

required to measure students' mathematical

communication skills on each item.

Before the instrument used, firstly the

instrument is piloted. This trial is intended to obtain

validity, distinguishing power, difficulty, and

reliability of the instrument. The data obtained were

analyzed using the test of difference of two averages.

The test formula used was t-test. To know the effect

of The Learning Cell model was used effect Size

formula (r2) (Kadir, 2015).

3 RESULTS AND DISCUSSION

Based on the data processing on the post-test

score on the aspect to be measured, those aspects of

the students' mathematical communication skills,

obtained post-test score for experimental group and

control group in Table 1 below.

Table 1 shows the acquisition of percentage of

first indicator of mathematical communication skills

that represent real object, drawing, and diagram in the

form of idea and or mathematical symbol in

experiment class is higher than control class, the

percentage equal to 56,10%. It is caused the students

in the experimental class who use The Learning Cell

especially at the stage of Openness, Social, Evolvable

& Context-Aware and Cohesive make students

command in representing images into ideas or

mathematical symbols. In addition, they command to

work out the problem systematically during the

learning activities and always concluding what has

been completed so that they can communicate

mathematical ideas well. But in the control class,

these activities are rarely performed. In indicator 2 it

explains ideas, situations, and mathematical relations

in writing using real objects, images, and algebraic

expressions, the percentage of experimental class is

62,50% better than control class that is 51,42%.It is

caused by the learning process in the experimental

class that apply Learning Cell model especially in

Social, Evolvable & Context-Aware and Cohesive

there are activities where students are given various

information related to the building of flat side space

either in the form of statement relating to the daily

occurrence and image description, then students are

trained to do it by writing in advance what

information is contained in the matter so they can use

the information available to answer the problem.

They command to solve the problems using their own

language and explain their answers with drawings or

diagrams if necessary to communicate their

understanding and mathematical ideas to their

classmates. It contrast to the control class in the

learning who does not involve the way to

communicate mathematical ideas with images,

diagrams or tables, the students feel little difficult

when finding the problem assigned to illustrate in the

form of drawings, diagrams, tables, or algebraic

expression resulting in a picture that has not made

perfect. In indicator 3 it states daily occurrence in

language or mathematical symbol or arrange

mathematical model of an occurrence, the percentage

of students' mathematical communication skills in

experiment class is better than control class, that is

82,27%. Because the experimental class students,

especially at the level of Openness, Social, Evolvable

& Context-Aware and Cohesive are familiar with

issues related to daily life, so they can solve problems

related to daily problems or mathematical situations

and then solve them with the language of

Advances in Social Science, Education and Humanities Research, volume 115

mathematics or compile a mathematical model to

solve a problem. While the control class students in

the learning process only emphasizes the formulas

that must be known to solve the problem it caused the

control class students have not been able to declare a

mathematical situation, especially in daily life and

they completed according to their own answers. Table 1 presents the comparison of students'

mathematical communication skills of the experimental class and control classes based on the three indicators. The percentage of achievement of the students' mathematical communication skills test in the experimental class is 66,96% while the percentage of students' mathematical communication skills in the control class is 54,07% or in other words the percentage of mathematical communication skills of the experimental class is higher than the students' mathematical communication in control class.

After hypothetical test of overall mathematical communication skills, tcount = 3,138 is greater than ttable = 1.663 so it can be concluded that H0 is rejected, while H1 is accepted. H1 states that with 5% error degree, the average value of the mathematical communication skills of the students whose learning using The Learning Cell as learning model is higher than using expository. In general, after analysing the results of research, there are several things that cause differences in the average value of the experimental class and control class, one of the reasons is the learning process conducted on the experimental class and control class. This finding means that the learning process with The Learning Cell that contains the Social, Evolvable, and Context-Aware stages is more useful to the students to improve their mathematical communication skills than expository learning. These findings are also in line with the opinion of LACOE (Mahmudi, 2009) which suggests that the appropriate way to increase the mathematical communication skills is in group discussions. This is also in line with Goldschmid's (1972) states that The Learning Cell can improve students’ learning achievement more significant when given "unannounced examination" than the students who use conventional learning. In addition to this opinion, the findings of this study also correspond to research conducted by Marta Cahyaningrum, et al. (2012) who found that the average learning outcomes of students whose learning using The Learning Cell were higher than the average learning outcomes of students who get conventional learning. During the learning process, students who use The Learning Cell model tend to be more active in exploring information and knowledge that has not been owned. These findings are in line with research conducted by Rita Khotimah & Mukhafifah (2011) founded that the influence of student learning activities on student learning

achievement mathematics. However, the findings of this study are not in line with the research conducted by Awa (2013) founded that the highest indicator of the students’ mathematical communication skills is to express or illustrate mathematical models into the form of mathematical ideas.

4 CONCLUSION

Based on the results of the study on the

mathematical communication skills of students in

SMP Negeri 3 Tangerang Selatan, it can be drawn

conclusions as follow:

1. The students' mathematical communication skills

who are taught with The Learning Cell model

classified as good compared to conventional

learning strategies. The highest to the lowest

achievement of the indicators of mathematical

communication skills of the two learning are

similar. The highest achievement obtained on the

indicator of the event's mathematical and the

contents of the event's mathematical relationships.

Or tables in the form of ideas and mathematical

symbols.

2. Learning uses The Learning Cell model

influences students' mathematical communication

skills. The students' mathematical communication

skills are taught with learning techniques of The

Learning Cell model is more effective in

improving students' mathematical communication

skills than those are taught with conventional

learning models.
